I like the player animation and character control. I see you implemented one way platforms, very nice!
I would start the player's walk cycle a bit faster so it doesn't look like he is gliding, perhaps. I like the push/pull idea but i had some trouble enabling the waterfalls, and didn't really get the mechanic until trial and error. I guess I basically thought i was swapping the state of the water back and forth, but I didn't understand why. Now I get it though.
and above the water fall is a platform that is just barely out of my reach which is usually bad for player comprehension.
I think I might have reached the end of your content after interacting with 2 puzzles?
This was really cool! I think it could make a cool game. It would help if the players friends helped guide them a little bit to interact with the elements a bit quicker and easier, so they understand the core mechanic right away. Great job!
Thanks for the comment, I appreciate it!
I think you may have gotten stuck on the air jump I mentioned in the submission page. It's not a difficult mechanic, but I honestly didn't really explain it, which definitely explains why you got stuck.
Also I get your issues with waterfalls, it makes sense that it could be a bit incomprehensible. Though I will say that part of the idea of the game was that the player would explore a lot of the gameplay through trial and error, I just need to make it enticing enough so the players wouldn't get discouraged :D
Thanks again for playing! I will keep your feedback in mind for the future.
